The second instance of the expression “one thing” occurs in the story of the man born blind who received his sight. Although it was clear that the Lord Jesus had miraculously healed him, the Pharisees did not want to believe the truth. Their repeated questioning expressed the unbelief in their hearts. After two interviews with the man himself, sandwiched around a third with his parents, they end up excommunicating him from the synagogue! They denied the supernatural power of the Lord, discredited the testimony of the blind man, exchanged the truth of God for a lie, and interpreted the evidence according to a worldview founded upon false assumptions. Sound familiar? That is because there is nothing new under the sun, and we see the same blind reasoning by evolutionists and those who deny God’s existence in our day.

At this early stage in his journey of faith, the blind man did not have answers to all the questions of the Pharisees. But he did not get into a debate or argument with them. His testimony spoke for itself! There was only one thing he knew at that moment: that though he had been blind since birth, the Lord Jesus had given him the miracle of sight.

Notice that he said, “One thing I know”—not one thing I “think” or “feel.” There was no doubt about it. The change in his life was obvious! Feelings come and go; they are unreliable; they go up and down; but the Word of God lives and abides forever. It is sure and reliable and unchanging! We can rest in the assurance of God’s Word, both for salvation and His present care in our lives. “For I know whom I have believed and am persuaded that He is able to keep what I have committed to Him until that Day” (2 Tim. 1:12).
